Abstract
According to several empirical studies US inflation and nominal interest rates as well as the real interest rate can be described as unit root processes. These results imply that nominal interest rates and expected inflation do not move oneβforβone in the long run, which is incongruent with theoretical models. In this paper we introduce a new nonlinear bivariate mixture autoregressive model that seems to fit quarterly US data (1953 : IIβ2004 : IV) reasonably well. It is found that the threeβmonth Treasury bill rate and inflation share a common nonlinear component that explains a large part of their persistence. The real interest rate is devoid of this component, indicating oneβforβone movement of the nominal interest rate and inflation in the long run and, hence, stationarity of the real interest rate.
